COFFEE URN.

Application filed November 30, 1920. Serial No. 427,292.

To all whom it may concern: 2

Be it known that I, ISAAC C. POPPER, a citizen of the United States,residing at New York city, in the county of New York and 5 State of NewYork, have invented certain new and useful Improvements in Cofiee Urns,of which the following is a specification. I

My invention relates to an improvement.

in coffee urns.

The object is to provide a combustion chamber for coffee-urns, in whicha portable fuel may be used, with adequate provision to supportcombustion, and to prevent the 5 flame from being interfered with, orextinguished by, drafts or air pressure.

This invention includes acombustion chamber constructed and-adapted tolit the base of a coffee urn and afford support,

therefor, this. combustion chamber having air-inlets and outlets formedtherein, and a drawer movably connected with the combustion chamberadapted to receive the portable fuel and approximately center it beneaththebottom of the urn when slid "in place and fastened.

In the accompanying drawings:

Fig. 1 is a view in perspective;

Fig. 2 is a horizontal section.

A, represents an urn such as used for keeping coffee hot in hotels,restaurants, dining-cars, and other publicplaces.

B, represents my improved combustion chamber. This preferablycorresponds in $5 shape with the urn, that is to say if the urn is ofcylindrical-form, the combustion-chamber is of similar shape, with aslight flare 1 at the top to receive and fit the outer edge of the baseof the urn, so that the 4.0 two when together substantially form acontinuation of each other, giving a neat and attractive appearance, andraise the urn the desired height above the support upon which it isplaced. The combustion chamber preferably has three horizontal rows ofholes 2, 3 and 4, the holes being conveniently placed about an inchapart, and'the holes of the center row 3 being slightly larger, it beingdesirable to make the holes of this row somewhat larger than the holesof the upper and lower rows.

A drawer C is fitted to slide in a pair of runners 15 therefor, in andout through an opening 5 in one side of the combustion chamber. Theouter plate 6 of this drawer is of a form to fit and close the opening5, andhas corresponding perforations to those in the combustion chamber,so that;

affords a support for the can 10'of fuel,

which, when in place is substantially gauged beneath the center of theurn, so that the heat from the burning fuel is centrally and equallydistributed over the bottom of theurn, and its. intensity is felt. atthe spot where it should bev applied and distributed The drawer isprovided with a handle 11,

. and connected with the inner end. of this handle is a catch as a meansfor fastening the drawer in place in the combustion chamber when closedby simply turning the handle.

Lugs 12, preferably three in number are equidistantly placed at the baseof the com-' i bustion-chamber as a means for screwing or bolting thecombustion chamber to the table or other support.

While the combustion chamber may be made of any approved metal, it ispreferable to use sheet-copper, nickle, steel or'the like.

By actual test, it has been found that an urn thus equipped with myimproved combustion chamber, with the perforations. as

disclosed, is an effectual means of not only supporting the combustionof the portable fuel, but as a meansfor preserving the flame unaffectedor influenced by either drafts or air pressure even in a rapidly movingdining-car, which obviously aflords a severe test.

I claim: through said opening and constructed and A cofiee urn made intwo interfitting sec arranged to receive, hold and properly tionsforming continuations of each other, place cans of fuel beneath the urnwhen 10 one an urn proper, and the other a combusthe drawer is slid inplace. 7 5 tion-chamber, .the bottom or combustion In testimony whereofI aflix my signature.
